Command line-based music player in Linux

According to my colleagues, I am an excellent command controller. I wrote a music player under the command line to meet my linux command requirements during the idle time of the latest project. Player exploitation technology: Python + GST (http://gstreamer.freedesktop.org/modules/gst-python.html) + Co according to my colleague, I am a full command control.

Player exploitation technology:
Python + GST (html "> Http://gstreamer.freedesktop.org/modules/gst-python.html) + Console parsing

Player self-sustaining operations:
1. play
2. Next
3. Previous
4. pause
5. view the playlist information
6. view the current playback information
7. stop (exit)

Take a look:


By analyzing the memory information dumped by meliae dump, the memory usage is less than MB, which is relatively small.
